The EEV Emission Standard * Europe - A stepping stone to Euro 6?
The creation of the EEV standard enabled the R&D man-hours and costs previously demanded in satisfying minor sectors of the market to be channelled more productively
Cardiff,UK -Automotive World, by Alan Bunting -July 15, 2010: -- It was back in 1999 that the EU authorities set both Euro 4 and 5 truck and bus emission limits and the dates for their implementation, even though Euro 5 standards were not scheduled to become law for all newly registered vehicles until October 2008. So, manufacturers had some nine years to progress their powertrain - including aftertreatment - technologies to meet the stringent Euro 5 requirements... Earlier rounds of commercial vehicle emissions legislation in Europe had been widely criticized by manufacturers, not so much for the NOx (oxides of nitrogen) and PM (particulate matter) limits themselves, but for the legislators' procrastination in setting the deadlines for compliance... As a result, the producers of diesel engines and their all-important fuel-injection systems and turbochargers were effectively asked to perform technological and manufacturing miracles in uncomfortably hurried development and production programmes... What is perhaps even more remarkable about the foresight shown in the EU legislators' 1999 emission law announcement was the inclusion of a further non-mandatory emission standard, which could have been called "Euro 5 plus". But in fact it was given the rather clumsy label of "EEV", which stands for "enhanced environmentally friendly vehicle"...
